GAS-PURIFIER.

SPECIFICATION forming part of Letters Patent N 0. 732,756, dated July 7, I903.

Application filed September 25, 1902. Serial No. 124,742. (No model.)

T0 at whom it may concern.-

' Be it known that I, ERNEST F. LLOYD, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Valve Connections for Gas-Purifiers, of which the following is a specification, reference being bad therein to the accompanying drawings.

This invention relates more specifically to an improved valve connection for operating two purifiers, so that the gas to be purified can be passed through both boxes in series, making either box first or through either one alone in case it becomes necessary to recharge the other box with fresh purifying material. The object of'my invention is to construct a system-of pipe connection for this purpose which is more simple, symmetric, and comprehensive than the system inpresent use and which accomplishes the purpose desired without the loss of much valuable space. To this end I have devised a system of connections wholly confined within the space ordinarily provided for between the purifier-boxes and without interfering with the ordinary use of such space for communication, while at the same time the valves are symmetrically alined, readily accessible, and comprehensively arranged for operation, all as more fully hereinafter described, and shown in the accompanying drawings, in which-- Figure 1 is a plan View showing myimproved system of piping for connecting two purifiers.

Fig. 3 is Fig. 2 is an end elevation thereof.

A and B represent two gas-purifier boxes supported side by side, with an open spaceO between them, and each provided with a suitable inlet D and outlet E upon their adjacent sides, all arranged and operating in the usual manner for purifying'gas byconducting it through the purifying material in the boxes.

F F are two separate crossovers connecting the inlet of each box with the outlet of the other box across the intervening space, whereby the two boxes are connected into a circulating system. Each of these crossovers is formed with an intermediate portion a a, re-

. spec tively, which extends in the center of the intervening space parallel with-the sides of the purifiers. By placing the inlets and outlets suitably out of line with each other the end portions of the crossovers are placed at right angles to said intermediate portions. Each of these intermediate portions is provided in the center with a stop-valve G and G, respectively, and th'ese'valves control the flow of the gas through the crossovers. The valves G G are preferablyso-called gatevalves, the stem of whichprojects upwardly, so that each valve may be operated from above.

H H are portions of the gas-main which pass into the space between the purifier-boxes and form, respectively, thejinlet and outlet pipes with which each crossover is connected at its intermediate portion orfopposite sides of the stop-valve, respectively, and in such manner that theinletsand outlets into said crossovers are'in the reverse order in the two crossovers. The connections between the inlet and outlet pipcs H H and the crossovers are made through the angle-valves I I and I 1 the casings of which form the angles in the crossovers and into the bottom of which the inlet and outlet pipes, respectively, communicate through ports 1' 1', respectively, controlled by valve-disks jj, respectively, having valve-stems Z Z, respectively, projecting upwardly through the casing into the space above. In this way each crossover has a group of three valves, the one G in the middle controlling the flow of gas through the crossovers F, and the two outer ories'l I or I 1 (one of which is opposite the inlet of one box and the other one opposite the outlet of the other box) controlling the flow of the gas into and from the crossovers in such manner that if the two end valves in either group are opened and the gate-valve G thereof closed while the end valves in the other group are closed and the gate-valve thereof opened the gas will circulate throughboth boxes inseries, the one having the valve opposite its inlet opened being the first in series. If, how over, only the two valves opposite the inlet and outlet of one of, the boxes are opened, (all other valves being closed,) the gas will circulate through that one box only. The operation of the system is thus very comprehensive, and mistakes in operating the valves are not liable to occur, as the operator can see at a glance the function which each valve performs and how the boxes are connected. At the same time no valuable space is occupied, as there is ample space for a platform between the boxes above the pipes, the valvestems of the different valves projecting above the platform in alinement with each other in the center of the platform being also made thereby very accessible.

The inlet and outlet pipes H H are preferably carried along the sides of the purifierboxes upon a level just below that of the crossovers.

It will be observed that the whole system of connection is very simple and requires a minimum of valves and length of pipe.

Instead of the inlet and outlet pipes H H entering into the space between the purifying-boxes both from the same side one may enter from the opposite side, necessitating only an obvious change.

Should it be preferred to have the inlet and outlet valves in the crossovers arranged in the same order in both crossovers, it may readily be done by arranging the crossovers as shown in Fig. 4, in which the intermediate portions in the two crossovers are in reverse directions.

Upon reference to Fig. at it will be seen that the pipe H is connected by inclined branch h with the valve I and also by inclined branch 7L2 with the valve 1 while the pipe-H is connected by inclined branch h with the valve I and by inclined branch 7L with the valve 1, whereby the flow may be either direct from the pipe H to the valve I or by inclined pas sage 7L2 of the valve 1 and communication be tween the pipe H and the valve 1 established by the passage 19 or through the passage lbs with the valve I.

Having thus fully described my invention, what I claim is- 1. The combination with two gas purifiers arranged side by side with an intervening space, of two crossovers in alinement with each other connecting by oppositely-disposed transverse pipes communicating with suitable inlet and outlet openings in the adjacent sides of the purifiers across the intervening space, an intermediate portion in each of said crossovers being arranged parallel with the sides of the purifiers, and a group of three valves in each of said intermediate porlions symmetrically arranged in each group in alinement with each other each having an upwardly-projecting stem extending into the space above the crossovers the central valve of each group controlling the flow of gas through the crossovers and the end valves respectively controlling an inlet and an outlet port into the crossover through which said crossover is adapted to be connected with independent inlet and outlet pipes extending lengthwise in the space beneath the crossovers.

2. The combination with two gas-purifiers arranged side by side with an intervening space and provided with suitable inlets and outlets upon their adjacent sides, of two crossovers in alinement with each other each connecting an inlet of one box with the outlet of the other box across the intervening space, each crossover formed alike with an intermediate portion arranged parallel to the adjacent sides of the purifiers and provided with three valves having upwardly projecting valve-stems, the center valve controlling the flow of the gas through the crossover and the end valves controllinginlet and outlet openings into and from said crossovers through which said crossovers communicate with gas inlet and outlet pipes, and gas inlet and outlet pipes with the inlets and outlets into the crossovers in reverse order in the said crossovers.

3. The combination with two gas-purifiers of the character described and arranged side by side with an intervening space, of two crossovers connecting said purifiers upon their adjacent sides across said intervening space, each crossover formed alike with an intermediate portion arranged in the center of the intervening space parallel to the sides of the purifiers and each provided with a group of three valves having operating valve-stems projecting upwardly into the space above the crossover, the central one of these valves controlling the flow of gas through the crossover and the end valves respectively controlling inlet and outlet ports in the bottom side of the crossover through which the crossovers communicate with inlet and outlet pipes re spectively in the ends of the crossovers adjacent to the inlet and outlet openings of the purifiers, and curved pipes connected with the gas-main and having portions extended in a plane below said crossovers and the con nections with the purifiers.

4. The combination with two gas-purifiers arranged side by side with an intervening space, of two crossovers and transverselydisposed pipes connected therewith and conmeeting the two purifiers across said intervening space upon a common level and adapted to form with said purifiers a gas-circulating system, a stop-valve in each crossover and inlet and outlet pipes extending lengthwise of the space between the purifiers on a level below that of the crossovers and communicating therewith respectively through inlet and outlet valves located respectively on opposite sides of the stop-valves and oppositely to the inlets and outlets of the purifiers, said valves forming angles in the crossovers.

5. The combination with two gas-purifiers arranged side by side with an intervening space, of two crossovers arranged upon a common level and connecting cross-pipes and suitable inlet and out-let openings in the adjacent sides of the purifiers across the intervening space, each crossover formed with an intermediate portion extending parallel to the sides of the purifier, a stop-valve ineach of ICC said intermediate portions having an upwardly-projecting valve-stem for opening and closing the valve, two angle-valves in each intermediate portion on opposite sides of the stop-valve having upwardly-projecting valve-stems and valve-casings forming the junctions of the intermediate portion with the end portions of the crossovers, and gas inlet and outlet pipes extending lengthwise in the space beneath the crossovers along the adjacent sides of the purifiers and having downwardly-curved portions and communicating with the angle-valves through ports in the bottom of the angle-valve casings.
